Summary: This study systematically analyzed the contents, compositions, and sources of polycyclic aromatic hydrocarbons (PAHs) in river sediments near an important energy and chemical base in northwest China. The results showed that PAHs in the region have complex sources and pose potential ecological and carcinogenic risks.

Summary: This study investigated the geographical distribution of PAHs in estuarine sediments along different latitudes in China, using a compound-specific carbon isotope approach to characterize the sources of PAHs. It was found that human activities significantly impact PAHs pollution in estuaries, with coal processing and biomass combustion being identified as the main sources of PAHs.

Summary: PAH contamination in the groundwater of the Hutuo River Basin in Hebei Province, China, is mainly attributed to biomass combustion, with wood, coal, and gasoline sources contributing the most, followed by oil and diesel sources, and natural gas combustion. The concentration of PAHs in groundwater is influenced by land use, with varying pollution sources contributing differently in different areas. Results of this study provide valuable insights for the prevention and control of PAH contamination in groundwater in the region.

Summary: The contamination of PAHs and PAEs in river sediments in China, particularly in some tributaries, is not well understood. This study investigated the distribution, sources, and risk of these contaminants in the Nenjiang River and the Second Songhua River in Northeast China. The results showed that the contamination levels were relatively low and posed negligible ecological risks, although BaA and certain PAEs may still have a potential impact.

Summary: This study examined the sources, pollution, and ecological risks of PAHs in the Wuhan section of the Yangtze River. Sediment was found to be a secondary release source for two- and three-ring PAHs and a sink for four- and five-ring PAHs. The dominant contribution of PAHs in water was from two-ring PAHs, while in sediments, it was from four-ring PAHs. Higher levels of PAHs were observed around industrial areas during the wet season, influenced by local industrial emissions and rainfall/runoff. Risk assessments showed low risks in water but medium risks in 44% of the sediments. Energy structure adjustment and stricter regulations are necessary to reduce PAH emissions.

Summary: This study quantitatively identified the sources of nine heavy metals in the sediments of the Bohai Sea and found that most metals were below detectable contamination levels. However, Cd and Hg were moderately to significantly enriched, posing potential risks to aquatic ecosystems. Anthropogenic activities and atmospheric deposition were likely the main sources of these two metals.

Summary: The study collected PM2.5 samples from three megacities in the Yangtze River Delta and analyzed their composition, finding that vehicle emissions, coal burning, and industrial emissions were the main sources of pollution. PAHs levels were found to pose potential health risks, and a combination of health risk modeling and PMF indicated that vehicular emissions and coal burning were the major sources contributing to cancer risk in the three cities.

Summary: This study assessed the risk of PAHs in sediments in the Wei River Basin, finding that PHE and FLT were the dominant compounds. The total carcinogenicity risk was low, while the ecological risk of individual PAHs was moderate.

Summary: The concentration of PAHs in sediments of the Beibu Gulf varies spatially and is impacted by point source pollution, with their environmental behavior influenced by atmospheric deposition and sediment-water partitioning. Risk assessment shows that PAHs are within safety thresholds. Source apportionment methods identify oil spills and oil and biomass burning as the major sources of PAHs in the sediments.

Summary: This study used high-precision Tl isotopic compositions to investigate the migration pathway and source apportionment of Tl in sediments from a pyrite mine area in south China. The results showed that anthropogenic Tl sources had the greatest influence on the Tl isotopic fractionation in the sediments. Additionally, a ternary mixing model revealed that waste from pyrite mining activities affected the downstream sediments up to 10 km. These findings highlight the significance of Tl isotopic signature in tracing Tl contamination sources and guiding targeted remediation efforts.

Summary: Little is known about pollutant concentrations in remote marine areas like the Porcupine Bank. Understanding the background concentrations in these areas is crucial for remediation and management strategies. Sampling in remote areas allows for better assessment of background concentrations without being impacted by historical or current inputs.

Summary: This study assessed heavy metal contamination in the surface sediments of the Bharalu river in India. The concentrations of Ni, Zn, Pb, and Fe were analyzed and their levels were found to exceed the sediment quality guidelines. The pollution indices and risk assessment methods used in this study revealed a higher contamination in the downstream sites compared to the upstream site. Anthropogenic sources, such as urban discharges and waste dumping, were identified as the main contributors to metal contamination in the river sediments. These findings emphasize the need for effective river management strategies to address heavy metal pollution and protect the river ecosystem.

Summary: This study investigated the concentrations and distributions of PAHs and aliphatic n-alkanes in surface sediments of the Lafayette River. Potential atmospheric sources were identified, and the potential consequences for human consumption were examined through analysis of oyster and crab tissues.

Summary: In this study, long-term measurements of PAHs in surface waters of seven river basins across China were reported. The pollution level of PAHs was higher in North China than in South China, with coal and biomass combustion identified as the main contributors. Some individual PAH concentrations exceeded environmental quality standards, and certain river basins were found to be at moderate or high risk of contamination.

Summary: The study assessed the levels of polycyclic aromatic hydrocarbons (PAHs) in sediments collected from the mouth of the Balsas River, Pacific Coast, Mexico. The PAH levels varied depending on the season and indicated anthropogenic activities in the region. The analysis of different ratios revealed a mixed source of PAHs from petroleum and biomass combustion. The evaluation also showed moderate pollution with adverse biological impacts and high levels of mutagenic and carcinogenic PAH compounds in the region.
